Use the Stop-DatabaseAvailabilityGroup cmdlet to stop a member of a database availability group (DAG) or to stop an entire Active Directory site. The Stop-DatabaseAvailabilityGroup cmdlet is used during a datacenter switchover. This cmdlet is used to mark the members of the DAG in a failed datacenter as stopped.

The Stop-DatabaseAvailabilityGroup cmdlet can be run against a DAG only when the DAG is configured with a DatacenterActivationMode value of DagOnly. For more information about DatacenterActivationMode, see Understanding Datacenter Activation Coordination Mode. You can use the Set-DatabaseAvailabilityGroup cmdlet to configure the value for DatacenterActivationMode.

Stop-DatabaseAvailabilityGroup -Identity <DatabaseAvailabilityGroupIdParameter> -ActiveDirectorySite <AdSiteIdParameter> [-ConfigurationOnly <SwitchParameter>] [-Confirm [<SwitchParameter>]] [-DomainController <Fqdn>] [-WhatIf [<SwitchParameter>]]

Stop-DatabaseAvailabilityGroup -Identity <DatabaseAvailabilityGroupIdParameter> -MailboxServer <MailboxServerIdParameter> [-ConfigurationOnly <SwitchParameter>] [-Confirm [<SwitchParameter>]] [-DomainController <Fqdn>] [-WhatIf [<SwitchParameter>]]

You need to be assigned permissions before you can run this cmdlet. Although all parameters for this cmdlet are listed in this topic, you may not have access to some parameters if they're not included in the permissions assigned to you. To see what permissions you need, see the"Database availability group" entry in the High Availability Permissions topic.


Parameter Required Type Description




The ActiveDirectorySite parameter specifies the Active Directory site containing the DAG to stop (for example, stop all members of the DAG in a particular Active Directory site).




The Identity parameter specifies the name of the DAG being stopped.




The MailboxServer parameter specifies a single member of the DAG to stop. If Datacenter Activation Coordination mode is enabled for the DAG and all DAG members are in the same Active Directory site, use the MailboxServer parameter to stop individual DAG members instead of the ActiveDirectorySite parameter when stopping failed DAG members.




The ConfigurationOnly parameter updates the Active Directory properties with the stop action, but doesn't perform a stop of the DAG or any members. This parameter must be used when the DAG member servers are offline, but Active Directory is up and accessible in the primary datacenter.




The Confirm switch causes the command to pause processing and requires you to acknowledge what the command will do before processing continues. You don't have to specify a value with the Confirm switch.




The DomainController parameter specifies the fully qualified domain name (FQDN) of the domain controller that writes this configuration change to Active Directory.




The WhatIf switch instructs the command to simulate the actions that it would take on the object. By using the WhatIf switch, you can view what changes would occur without having to apply any of those changes. You don't have to specify a value with the WhatIf switch.

To see the input types that this cmdlet accepts, see Cmdlet Input and Output Types. If the Input Type field for a cmdlet is blank, the cmdlet doesn’t accept input data.

To see the return types, which are also known as output types, that this cmdlet accepts, see Cmdlet Input and Output Types. If the Output Type field is blank, the cmdlet doesn’t return data.


Error Description

This command can only be run on a database availability group (DAG) when the DatacenterActivationMode parameter for the DAG is set to DagOnly. (Error 3EBE1F79)

Indicates that Datacenter Activation Coordination mode isn't enabled for the DAG. Use the Set-DatabaseAvailabilityGroup cmdlet to set the DatacenterActivationMode parameter for the DAG to DagOnly.

This example stops the Mailbox server E14EX2 in the DAG DAG1.

Stop-DatabaseAvailabilityGroup -Identity DAG1 -MailboxServer E14EX2

This example stops all members in the DAG DAG1 in the Active Directory site Redmond.

Stop-DatabaseAvailabilityGroup -Identity DAG1 -ActiveDirectorySite Redmond

This example stops the Mailbox server E14EX3, which is currently offline, in the DAG DAG2.

Stop-DatabaseAvailabilityGroup -Identity DAG1 -MailboxServer E14EX3 -ConfigurationOnly
